Exposing mice with the autism-associated SHANK3 genetic mutation to new environments can trigger autism-like behaviors, including repetitive movements and problems with social engagement. However, adding familiar objects to the novel environment during the first exposure can reduce the behavioral and brain signaling deficits.
A new theory suggests the brain understands the level of activation required from a sensory input and corrects for it, leaving behind a signal for familiarity.
Researchers propose a new theory of what happens in the brain when we experience familiar seeming visual stimuli. The theory, dubbed sensory referenced suppression, suggests the brain understands different levels of activation expected for sensory input and corrects for it, leaving behind the signal for familiarity.
When intense feelings of prediction accompanied deja vu, they were strongly correlated with feelings of postdiction. High degrees of familiarity that accompany deja vu also carry through to postdictive bias.
A new study reveals that people tend to perceive familiar faces as looking happier than those they are not familiar with.
Researchers take control of rats' brains to induce the animals to behave as those new images were familiar and old images were novel, a new study reports.
According to a new study, familiarity plays a crucial role in memory and learning.
